Voidsworn: Idle Tower Defense

A lone dying star holds the line against the void.

Voidsworn is an idle tower defense game. Your Core fights endless waves of void creatures on its own, and you decide how it grows. Short, active runs feed a Reactor that keeps earning while you're away.

If you love idle games, incremental progression, tower defense and watching your defense grow stronger with every run, Voidsworn is built for you.

THE LOOP
• Deploy and watch the Core fight. Kills drop Sparks: spend them mid-run on Attack, Defense and Utility upgrades.
• When the Core falls, or you retreat, bank the Stardust you earned.
• Spend Stardust in the Workshop on permanent upgrades, and research new tech in the Lab.
• The Reactor fills with Stardust while you're away. Collect it and go deeper.

SURVIVE THE VOID
Every run is a fight for survival. Enemies speed up and grow tougher the deeper you go, bosses test your build, and each tier asks for a new strategy. Retreat to bank your gains, or push for one more wave and see how far the Core can burn.

WHAT'S INSIDE
• 13 difficulty tiers, from Drift to Entropy, each with its own milestone Reward Track.
• Boss waves with their own threats, and new void species as you go deeper.
• 33 collectible Cards that change how your Core fights: lasers, orbitals, stasis fields and more.
• A deep Workshop of permanent upgrades that make every run stronger.
• A deep Lab research tree, including faster battle speeds.
• Powerful Ultimates you can trigger mid-run to turn a losing wave around.
• Equippable Modules, unlocked at Tier 7, that add new ways to customize your Core.
• Daily Ops: a daily supply drop plus rotating directives.
• A global leaderboard.
• A quick first-run tutorial that gets you into your first run in moments.

DEPTH IS PROGRESS
Reach a set wave on one tier to unlock the next, claim checkpoint rewards along the way, and watch your best wave climb. Early tiers teach the basics in minutes; later tiers reward careful builds and patient research.

BUILD YOUR DEFENSE
Every choice matters. Spend Sparks mid-run on Attack, Defense and Utility upgrades. Bank Stardust to strengthen the Core permanently in the Workshop. Research new tech in the Lab. Collect and level Cards to reshape your weapon systems. Mix them together and find the build that carries you past your best wave.

IDLE PROGRESS THAT RESPECTS YOUR TIME
Voidsworn is made for short sessions. Launch a run, upgrade on the fly, then put your phone down. While you're away the Reactor keeps generating Stardust, and when you return a Welcome Back report shows what you earned. An optional rewarded video can boost what you collect, but it is always your choice.

PERFECT FOR FANS OF
Idle games, incremental games, tower defense, auto-battlers, space defense and sci-fi survival. If you enjoy upgrading, optimizing and pushing a little further each time, you'll feel at home.

QUICK TIPS TO GET STARTED
Put your first Sparks into Attack, then balance Defense as waves toughen. Bank your Stardust after every run and spend it in the Workshop. Start a Lab research before you leave, since research takes real time and keeps counting down while you're away.
